You are welcome. With AO-51's pass times creeping earlier and earlier, 
we may have to move the mode changes to the morning passes. A 5:45PM 
pass is not easy to make when one has to be at work until after 5:00PM 
and has a 45 minute commute.

The power on the repeater downlink is a bit higher than normal at 760 
mw. It shouldn't be a dramatic difference from our recent 500-600mw, but 
noticeable to a observant operator. The spin rate is also slowing 
dramatically, up to ~13 min per rev, so any fades should be nice and 
slow, although long.
